摘　　要：采用程序升温热重法研究了飞灰/CO2高温气化反应性。结果表明:随着升温速率的增加,不同飞灰炭气化反应性的变化程度有所不同;SCFA的气化反应性高于HLFA和NCFA。脱灰后飞灰炭的反应性变差;飞灰炭的气化反应性优于高温煤焦。The CO2 gasification characteristics of three fly ash samples were performed by a temperature-programmed thermo-gravimetry.The results showed that heating rate had obvious effects on CO2 gasification reactivity,that the reactivity of SCFA higher than that of HLFA and NCFA.In general,the gasification reactivity of fly ash carbon was better than of the coal chars,and the reactivity of demineralized fly ash carbon was worse.
